'''Function details:''' 
Any entry in [[:Category:Candidates for speedy deletion by user]] is checked for
simple compliance with CSD-G7: a single contributor <u>talk <s>or User</s></u> page.  <s>If that page is in 
User: or User Talk: the contributor must also be that user.</s> 
Pages are required to have one of the appropriate templates - {{tl|db-g7}}, {{tl|db-self}}, {{tl|db-author}}, {{tl|db-blanked}}.
<u>Redirects created by moving pages or pages that are transcluded anywhere will not be deleted.</u>

Complying pages are deleted; <u>no confirmation is given to the requesting user - the delete just happens</u>.  Checks against the category are run every 30 seconds, so the average turn-around will be about 15 seconds.  

<s>Pages are not tested for having one of the appropriate templates, for example {{tl|db-g7}}</s>

CSD-G7 allows for pages other than those with a single contributor to be deleted (no substantial contributions from others), but that requires judgment and so the bot will only delete those with a single contributor.

<!-- This is not a vote.  It is a discussion -->
I developed the bot in response to [[User:Bwilkins]]' request, but as a non-admin I can't operate it.  It would be prudent for a code-review to be undertaken given the bot will have administrator powers.  Source code runs to 111 lines.

Some comments from reviewing the code:
* Why doesn't it check for the presence of the template? Every once in a while, someone tags a template with a CSD tag and forgets to put it in <nowiki><noinclude></nowiki> tags. If someone tagged a userspace template (like a userbox or a header template), the bot might accidentally delete half their userspace.
* G7Bot.number_to_fetch seems be be unused
* <code>match = re.search('User( Talk)?:(?P<username>[^/]*)/?.*?', page.title())</code> — The 'talk' in 'User talk' is not capitalized
*In function G7Bot.delete_page(), the continue statement isn't directly in a loop, so that won't work.
*I'm also not sure if the username check for userspace its necessary. You're already checking that the page only has one contributor, the only thing this would do is not delete a page if someone created the page in someone else's userspace for some reason. But since they're the only editor, it would still technically fall under G7.
*<code>page.Delete(reason='Simple compliance with G7',</code> - This is unnecessarily non-descriptive/cryptic. I would add a link to [[WP:CSD#G7]] and a short description of what this means, similar to the deletion summaries used by Twinkle.
*Is pywikipedia maxlag compliant by default?

:Mr. Z-Man- pywikipedia has a function to set throttle automatically, but it can be overridden if need be. 
:Just a few things:
:#For accounts with a bot or admin flag, the API allows for 5000 items instead of only 500. 
:#I agree with Mr. Z-man that you do not need to check the username; if there is only one contributor the page is delete-able. 
:#With that in mind the enitre <code>only_contributor(page)</code> module is not needed. Instead use wikipedia.page.contributingUsers(). That module returns a set of all users who have edited the page. I assume you could use something like:

 if len(page.contributingUsers()) <= 1:
    page.delete()

;Rewritten to reflect code review
The the need for a template-check was a particularly good catch. If there are alternative suggestions for the delete summary message, which now reads ''Only one contributor who requested deletion under [[WP:CSD#G7]]'', please bring them forth! Yes, pywikipedia is maxlag compliant by default. 500/5000 doesn't make much difference, you're never going to see that many in that category unless something goes horribly wrong.

*'''Support'''. In general, I think this is a worthwhile project that will help handle a generally non-controversial corner of the deletion process. That said, I'm not sure we'll see that many pages compliant with the criteria above. If a user starts an article, then blanks it, the user that tags it as G7 becomes the second editor. I don't imagine anyone would object to the deletion of the page, if the last edit was to tag it and all preceding edits were the author, and if the next-to-last edit (immediately before the tag) were an edit flagged as "Page Blanking". But I have no idea how you'd code it, nor do I know if it would be worthwhile to code so narrow an exception. An aside - does the bot notify the user, even with something as simple as "{{done}} - [[Example]] has been deleted per your request. [[Wikipedia:Bots/Requests for approval/7SeriesBOT|User:7SeriesBOT]] 14:09, 2 February 2010 (UTC)"? In any case, brilliant work and I look forward to seeing this.

*:Admins don't notify so I don't see why a bot would need to.

*::Meh, I usually notify if I delete a G6 - but it's more of a "Page is deleted, so you can do your page move/housekeeping/whatever". I think it is useful to notify a new user if their article was deleted just because they blanked it, if only as a measure to combat [[WP:BITE]]ing - but agree, it's usually unnecessary. A list of bot notices would be helpful in tracking the bot's activity, though - and might not be a bad idea during any trial period.

*:::In a case like that I look for a clear indication, usually beyond mere blanking, that the '''author''' wanted deletion. Absent such, I wouldn't delete. I also check for significant items in history that shouldn't be deleted, and of course would not usually delete a user talk page under G7 or G6, or U1. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 03:50, 3 February 2010 (UTC)
*'''Support the idea''', as long as the bot's able to delete pages that have been edited by another user who does nothing but placing the deletion tag.  Like Xeno, I don't know coding, so I have no opinion on whether this version of this bot is good.  [[User:Nyttend|Nyttend]] ([[User talk:Nyttend|talk]]) 15:46, 2 February 2010 (UTC)
*'''Support the general idea''' so long as it disregards "contributors" who only added the G7 tag (plus optional whitespace). One other point: in order to make only uncontroversial G7 deletions, it probably should not delete pages in article space if there has been any previous AfD for that pagename. It isn't especially likely that an article creator nominated his own page for AfD, AfD returned keep, and the nominator then tagged the page as G7 - but it is possible, and in such a case the page should not be speedily deleted. <span  style="white-space:nowrap">— [[User:Gavia immer|Gavia immer]] ([[User talk:Gavia immer|talk]])</span> 17:57, 2 February 2010 (UTC)
*'''Strong oppose''' I deal with many G7s at CSD:SPEEDY, and although I delete the great majority of them,  it is not always as simple as it looks, even when there is only one editor.  Once they have contributed a page, people no longer own it. If they should give up on developing it, someone else still might. I will not delete it if it looks like it might be a passable article--to avoid confusion I edit it a little in that case. People have even sometimes marked their pages for deletion out of spite, sometimes when leaving Wikipedia, or sometimes  from pure impatience with our processes. But the main reason I oppose is that we should do nothing which in any way lets people think they have OWNERSHIP. '''[[User:DGG| DGG]]''' ([[User talk:DGG| talk ]]) 19:02, 2 February 2010 (UTC)
*'''Oppose''' - per DGG, and because this has been discussed before with a conclusion that there are too few cases to justify a bot. Also it sets a "deletion by bot" precedent which we should be careful about doing; I don't think the gains here are large enough to justify the precedent.

*'''Comment''' In my experience g7 tags are often used in userspace too instead of u2 tags, since they're basically saying the same thing.

* '''Comment''' I originally came across Josh's bot dealing specifically with article talkpages that WildBot had been marking to fix disambiguation issues, then would blank the talkpage and mark for G7.  This still generates a lot of article talkpages for speedy deletion.  I would have no issue whatsoever (and it originally was my intent) for this to focus ''solely'' on those article talkpages that get tagged for G7 by Wildbot.  Any future tasks could be added later on, if the simple G7'd article talkpage was a successful project.

*'''strong oppose'''', as per DGG. I find that G7 tags are often misapplied. I do not trust a bnot to make the needed distinctions, and i am dubious about a bot with delte tools at all.

*'''Oppose''', not necessary (volume is clearly manageable), might cause problems every now and then.

===G7 "good faith" requirement===
It appears all the opposes are on the difficulty of measuring the G7 "good faith" requirement, which is a perfectly reasonable objection.  

The original rationale for developing this bot is WildBot's activities, which often result in a blank talk page which can be a confusing thing to see.  It was suggested that WildBot tag talk pages that it was the only contributor to with G7 to avoid this, but then there was a raft of admins complaining about the vast number of blank talk pages they were being asked to delete.

Would it be reasonable for 7SeriesBOT to limit its activities to all talk pages, and any User: page?  If not, what about deleting pages which only have bot contributors; or a single bot contributor? [[User_talk:Josh Parris|Josh Parris]] 05:46, 3 February 2010 (UTC)
:Frankly i think it would be better for wildbot to simply blank the page, and not worry about deleting it. in most of the cases where it acts, a project template belongs on the talk page anyway. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 06:14, 3 February 2010 (UTC)
:I should add that I oppose on principle any bot intended to do page deletions, for whatever purpose and under whatever safeguards. Also in this particular case, a request may be made in good faith, but there may still be a valid reason to decline it. Talk pages (not user talk) with only a single bot contributor is less dangerous, I will grant. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 06:18, 3 February 2010 (UTC)

:::Not automagically.  There are dozens of bots whose role in life is to tag pages for WikiProjects, but they're all semi-automatic - the operator will tell them to, for example, tag every article that appears in both of these two categories (or sub-cats thereof) as belonging to WikiProjects XYZ, and off the bot goes.  But categorization is something new pages only sometimes get, and often poorly at that.  There are many techniques for project tagging, but of 229 early talk pages deleted after WildBot blanked them, only 20% have been recreated (some possibly by WildBot) - see [[User talk:WildBot/NukeFromOrbit]].

'''Question''' Clue me in, why could deleting a single-contributor User Talk: page at the contributor's request be a bad idea? [[User_talk:Josh Parris|Josh Parris]] 11:10, 4 February 2010 (UTC)

===Backing up for a few minutes to refocus===
Allow me to review a couple of things about Josh's bot.  From my understanding, it checks an article, finds disambig issues, notes them on the article's talkpage, checks later to see if a human has fixed them, and eventually removes the checklist from the talkpage.  Up until recently, it would also then tag that talkpage as G7 iff it was the sole contributor to the page.  In other words, it creates a shopping list, waits for someone to deal with the shopping list, therefore leaving a history of those changes on the article itself.  Once you've bought the groceries, you can throw the list away.

The intent of this bot is to basically follow behind Josh's bot and throw away the shopping list - the history of actions taken ''already exist'' on the article.  Blanking the page completely looks bad (lets say it the article itself gets CSD'd and someone puts a hangon tag on but does not edit the talkpage ... a redlinked talkpage is actually faster to deal with).

For now, I would suggest that we not expand the nature and tasks of the bot beyond this simple task that would still generate close to 100 edits per day, that is if Josh's bot goes back to tagging shopping lists as G7 again.

Maybe we can have a G7m ("G7 maintenance has been performed by bots only") tag and category ... Josh's bot could tag them in this category, and the bot up for discussion would only track articles inside that category and immediately remove before additional adminstrative investigation and work would be required?  It would still, of course, check that there had indeed only been one editor to the talkpage, and could check if it was indeed WildBot.

What could be a simple task - and a valid follow up to an already approved bot seems to me to be expanding in complexity in its early days.  It can already save at least 100 manual deletions (and the work behind them) if implemented in this manner.  ([[User talk:Bwilkins|<span style="font-variant:small-caps;">talk→</span>]]<span style="border:1px solid black;">'''&nbsp;[[User:Bwilkins|BWilkins]]&nbsp;'''</span>[[Special:Contributions/Bwilkins|<span style="font-variant:small-caps;">←track</span>]]) 13:14, 4 February 2010 (UTC)

:I will admit that if restricted to talk pages created only by this bot, or indeed only by some bot, and edited only by one single bot, there seems no particular risk. The previous proposal, in which the bot aimed to handle any G7 tag was a different matter. My only concern remaining would be for precedent, I don't know of a previous bot authorized to delete pages, and I am wary of this being a precedent for delete-bots not quite as constrained, or for a later expansion of this one. I also don't see leaving the blank pages around as so much of a problem, so i don't see the pressure for this bot. But I admit that those are significantly weaker arguments, and my opposition has therefore gone from "strong" to "weak". [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 14:24, 4 February 2010 (UTC)

:Personally, I'm not quite sure I see the problems with the original proposal.  I don't think that the problems were so insurmountable that they required scrapping the original proposal entirely. Most of them could be mitigated almost entirely by checking transclusion count and creation date (verifying the page isn't used as a template anywhere and it has only existed for <X days). Even if it didn't do these, I don't think I've ever turned down a G7 or U1 deletion outside of user talk-space. Even if somehow a page that shouldn't be deleted was, deletions are easily undone (it could also check the deletion log and refuse to delete the same page twice, or refuse to delete any page that's already been deleted once before). As for precedent, [[User:AntiAbuseBot]] was used to delete various abusive user talk pages, [[User:Cydebot]] deletes categories after moving them, [[User:MPUploadBot]] deletes images that were temporarily transferred from commons for use on the main page, [[User:Orphaned talkpage deletion bot]] deletes orphaned talk pages, and [[User:Yet Another Redirect Cleanup Bot]] deletes broken redirects. So there's certainly plenty of precedent for adminbots that do deletions. <span style="font-family:Broadway">[[User:Mr.Z-man|Mr.]][[User talk:Mr.Z-man|'''''Z-'''man'']]</span> 16:51, 4 February 2010 (UTC)

::Being a non-administrator, I have to defer to the opinions of those who are experienced in this area; DGGs point about ownership was perfectly reasonable, and I'm quite happy to have the bot defer these judgment issues to humans - I don't want editors taking their bat and ball and going home, and having 7SeriesBOT facilitate that.  I hadn't considered this, but that's due to lack of experience in this area; Bwilkins never asked for a scope increase and I didn't even consider that scope increase could be a problem. Even with an age check on an article, it could be something substantial worked up offline, posted and then retracted in short order; I'd feel more comfortable with a human screwing up and deleting that than with a bot just automatically doing so without anyone noticing what had happened.  Off the top of my head I can't think of any metric that could reliably distinguish between a useful human-written article and a substantial algorithmically generated page (I'm anticipating eventually WildBot could be making quite large talk page entries), so I can't see any safeguard against this kind of (rare, but costly) outcome.

:I agree with DES that a bot deleting talk pages created only by that bot would make sense. We can think of them as temporary, and having served their purpose. In spite of the potential for slipping into something broader, I sufficiently trust Josh's caution that I would support a trial of it.  As Z-man points out, there are other possible similarly very limited functions.   I still have a vestigial feeling of wanting to clean up,  due to having grown up on systems with limited storage.

(unindent) in view of obviously developing consensus, consider my objections to the modified proposal withdrawn. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 00:37, 5 February 2010 (UTC)
:I agree with Mrz-Man: The original proposal was fine. In fact, I think we can even do away with the "If the page has existed for less then X days" part. Whe the only person who ever contributed to a page and wants it gone, the page is delete-able (under the CC-BY-SA). Let the bot run full time, on all {{tl|db-g7}} requests. [[User:Tim1357|Tim1357]] ([[User talk:Tim1357|talk]]) 12:40, 5 February 2010 (UTC)
::That I would object  to, strongly, as per my comments above. At the very least if the page is not a talk page, the bot would have to check that the corresponding talk page had no edits by anyone else -- this is required by [[WP:CSD#G7]].  And general G7 deletions are not so common that a bot is needed for them in any case. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 15:59, 5 February 2010 (UTC)
::: Yes, I agree, as does everyone else, that the page can only be deleted if there is only one contributor ever. This follows the [[WP:CSD#G7]] policy just fine. The argument that 'general G7 deletions are not so common that a bot is needed for them in any case.' is invalid. If a bot can do a task without harming anything, and helps in some tangible way, then it is appropriate. [[User:Tim1357|Tim1357]] ([[User talk:Tim1357|talk]]) 22:02, 7 February 2010 (UTC)

====Code available====
Revised code is now available for review; it implements the functionality currently described for the BRfA. [[User_talk:Josh Parris|Josh Parris]] 11:20, 8 February 2010 (UTC)
:Please clarify, this implements the "modified" proposal: i.e deletes only talk pages, whose only contributor is a single bot account? [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 01:54, 9 February 2010 (UTC)
::I'll repeat the function overview, minus all the markup:
::''Any entry in Category:Candidates for speedy deletion by user is checked for simple compliance with CSD-G7: a single contributor talk or User page. Pages are required to have one of the appropriate templates - {{tl|db-g7}}, {{tl|db-self}}, {{tl|db-author}}, {{tl|db-blanked}}. Redirects created by moving pages or pages that are transcluded anywhere will not be deleted.''
::''Complying pages are deleted; no confirmation is given to the requesting user - the delete just happens. Checks against the category are run every 30 seconds, so the average turn-around will be about 15 seconds.''
::''CSD-G7 allows for pages other than those with a single contributor to be deleted (no substantial contributions from others), but that requires judgment and so the bot will only delete those with a single contributor.''
::At this time, that doesn't say "bots only", and it also includes user pages, but other than that it matches your description.  No one offered any reason as to why single human-contributor talk pages ought to be treated differently from bot-contributor ones. [[User_talk:Josh Parris|Josh Parris]] 02:39, 9 February 2010 (UTC)
:::Why do you not include other namespaces? As long as they have only one contributor they meet the standards of CSD-G7. [[User:Tim1357|Tim1357]] ([[User talk:Tim1357|talk]]) 03:19, 9 February 2010 (UTC)
::::In any namespace other than User, if a G7 is placed on a non-talk page, edits to the corresponding talk page must also be considered. Indeed this is also true in the user namespace if the page under discussion is not the main user page. That is if [[User:Example/draft article]] has been edited only by [[User:AAA]], but [[User talk:Example/draft article]] has been substantially edited by [[User:BBB]] and [[User:CCC]], then a G7 by [[User:AAA]] should be declined. (of course a U1 speedy by [[User:Example]] would be proper, and why [[User:AAA]] is creating a page in another user's space is unknown)
::::I therefore suggest a modified set of pages on which the bot would operate:
::::*A Talk page with a single contributor, or
::::*A User page with a single contributor who is the user in whose user space the page lies.
::::Otherwise as in your proposal above. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 05:08, 9 February 2010 (UTC)
:::::So, you're on board with single-contributor talk pages, but for user pages think the single contributor should be that user space owner.  It is a good question: Why would someone create (and then request deletion of) a page in someone else's user space? I don't know; that would be fairly odd.  Can you think of any reason not to honor the request?  I think I'm asking: would the project lose anything by automatically allowing that deletion? [[User_talk:Josh Parris|Josh Parris]] 05:42, 9 February 2010 (UTC)
:::::Oh, User main pages would be included in this, is there anything special about how admins treat them? [[User_talk:Josh Parris|Josh Parris]] 05:42, 9 February 2010 (UTC)
::::::It is not a highly likely situation, but if a page is placed in userspace then unless the contributor is the user (when U1 also applies, and the question of which tag is used becomes mere procedural trivia) then if the corresponding user talk page has been edited by a different user, perhaps with suggestions for the user page (which may be an article draft) the page should not be deleted. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 06:06, 9 February 2010 (UTC)
::::::Also in the rather unusual case where a user creates and then wants to delete a page in another user's userspace, it is not a bad idea to have an actual human look at the page and possibly look into what is going on, IMO. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 06:06, 9 February 2010 (UTC)
::::::Indeed the most likely reason i can think of for a user to create a page in another user's space is as a cut&paste method of userfying a deleted or about to be deleted article. In such a case attributions may be missing from the history, perhaps covered by {{tl|copied}} in the talk page. In such a case, any admin should decline the G7. Not common i'm sure, but possible. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 06:19, 9 February 2010 (UTC)
:::::::I think in light of that, it's best to strike User: space from the proposal. (done) [[User_talk:Josh Parris|Josh Parris]] 08:32, 9 February 2010 (UTC) 
::::::::Given that I have no further issues with this request, and support approval. Sorry if it has been a problem agreeing on parameters here. [[User:DESiegel|DES]] [[User talk:DESiegel|<sup>(talk)</sup>]] 16:49, 9 February 2010 (UTC)
:::::::::The BRfA process is intended to avoid bots making mistakes that could have been foreseen.  Arduous though the process can be at times, in the end we have a product that's going to cause as little screaming as possible, and that is very much worth the angst.  It does a wonderful job of preventing bone-headed ideas getting through. [[User_talk:Josh Parris|Josh Parris]] 00:18, 10 February 2010 (UTC)
:::Tim, there's also the potential problem of someone making a GFDL gift and then retracting it (perhaps in a fit of spite) - I view this one as an intractable problem.  It's pretty safe to say single-contributor talk pages that the author wants to delete are not going to be any loss to the project; the same can't necessarily be said of other namespaces. [[User_talk:Josh Parris|Josh Parris]] 05:42, 9 February 2010 (UTC)
====Reviews invited====
Code runs to 155 lines and includes two non-library API calls; when trial-time comes I'm be throwing in edit-limiting code on top. [[User_talk:Josh Parris|Josh Parris]] 00:18, 10 February 2010 (UTC)

:{{BotTrial|days=7}} Ok, I think there appears to consensus. However, before the bot gets a flag or gets sysop-ed, I think you should do a dry run. I suggest tweaking the code so that the bot keeps a log of pages that it ''would'' have deleted, and later saving the log to [[/Dry-Run 1]] for review. Good luck! [[User:Tim1357|Tim1357]] ([[User talk:Tim1357|talk]]) 03:30, 11 February 2010 (UTC)

::Sources updated to reflect trial conditions, operator notified; it will live update [[User:7SeriesBOT/Dry-Run 1]] while running from start-up; each entry will include the reason not to delete and a link to the page in question's history.  Admins are probably best placed to review go/no-go calls by the bot once an article has been deleted, but anyone can check the difference between the bot's decision time and the human's decision time. [[User_talk:Josh Parris|Josh Parris]] 07:01, 11 February 2010 (UTC)

::Output is broadly similar; 7SeriesBOT doesn't mention the positive flags it notes (just the first negative flag), and it doesn't list contributors when there are multiple contributors; it does list article, reasoning, a link to article history and a timestamp. [[User_talk:Josh Parris|Josh Parris]] 22:00, 11 February 2010 (UTC)
'''Note:''' Bot was started in trial mode Feb 12, AM.  If WildBot was still tagging talkpages as G7, the bot would likely be more active.

{{od}}While I think this bot should be working on '''all''' namespaces, you can add the following to the 'params' in pages_in_category:
 params['cmnamespace'] = '1|2|3|5|7|9|11|13|15|101|109'
... which will limit the API result to the User-space, and all Talk-pages. [[User:Tim1357|Tim1357]] ([[User talk:Tim1357|talk]]) 01:15, 15 February 2010 (UTC)

*'''Update''' Bot ran for a couple of days without logging (fixed yesterday - see description on [[User talk:Josh Parris]].  Interesting issue with the tasks/policy as written: those who can see the deletion logs for [[Talk:ENI_award]] can see that one user created, then blanked the talkpage ... because someone else then tagged it for CSD, the Bot was unable to act.  Bot is limiting itself to talkpages only - this would become busier if WildBot went back to tagging talkpages accordingly.

===Trial complete===
{{BotTrialComplete}} Because of the couple of days of non-logging, I have let it run longer.  From my view of the logs, the Bot has been consistent and tagging "delete" only where appropriate.
